If you’re the proud owner of a new iPhone 5S, you’ve likely said goodbye to the traditional four-digit passcode and hello to Touch ID. Apple’s upgraded security feature lets users unlock their phones quickly and easily with their unique fingerprint.

But what about those techies who have yet to splurge on the latest iPhone? And what about the people who have iPhones but don’t use the passcode option? Apple claims that more than 50% of users don’t lock their phones with a passcode. After all, it can be a pain to punch in four digits every time you check your phone–which is an average of 150 times per day, according to Kleiner Perkins Caufield & Byers’ annual Internet Trends report.

Although a misplaced or stolen iPhone can be relocated with the free Find My iPhone app, that doesn’t prevent the device–or the data it stores–from being compromised. The best way to protect your device and the data on it is to not lose it in the first place. Luckily, a technology trend called “wireless leashes”–a concept similar to the invisible fences that keep your dog in the yard–can help prevent loss and, in turn, theft.

ZOMM is a poker-chip-sized device that wirelessly tethers to your Bluetooth-enabled mobile phone. ZOMM alerts you if you and your phone should ever separate by more than 30 feet. Clip ZOMM to your keychain or throw it in your purse. An alarm will sound the next time you’ve left your phone behind at the restaurant, in the taxi or at a friend’s house.

ZOMM is just one of the recent developments in cell phone safety, like the Bluetooth-enabled Tile system, that we’ve recently blogged about. But ZOMM takes safety to another level–and even doubles as a Bluetooth speaker. Say your phone rings while you’re driving but it’s buried at the bottom of your purse. Just click the ZOMM device that’s now hanging from your keychain and start chatting away.)
